24-034 PERCOLATION AND GROUNDWATER TESTING FOR A SEPTIC SYSTEM

DRAINFIELD AT WYOMING NATIONAL ELK REFUGE (NER)

I. GENERAL PROJECT SCOPE

A. The contractor shall provide all material and labor required to perform percolation testing to determine soil data for an individual septic system design. Contractor shall perform groundwater monitoring at the site. The groundwater monitoring testing method shall be recommended by the contractor. The data collected will also be used for the individual septic system design. Period of Performance: August 1, 2026 –

October 31, 2026.

It is recommended that the contractor review the project site prior to field work and testing. Access to the project site shall be coordinated with Sean Brophy sean_brophy@fws.gov

B. The contractor shall provide 3-ft below ground surface trench with excavation equipment. Additional 12 inches for percolation test holes shall be excavated by hand within the excavated trench. A minimum of 3 percolation tests shall be performed.

The contractor shall meet minimum requirements set by Teton County.

C. The contractor shall also observe all soil profile pits and shall be extended 8 ft below ground surface.

D. A qualified Geotechnical Engineer shall log the profile pits.
